name: Build valia-sites-sync

# ADR-0002 + ADR-0018: infra-owned image built off-infra on GHA → ghcr (public).
# Rclone + wrangler runner for the Valia-sites Content-folder mirror CronJob.
# Rebuilds are rare (tool pins only change deliberately) → dispatch + path.
# Security note: no untrusted event inputs are interpolated anywhere (only
# github.actor / github.sha / GITHUB_TOKEN — same shape as the other
# build-*.yml workflows in this repo).
